I try to do a timer in React but I have a problem, I have this problem Uncaught TypeError: Cannot read property 'seconds' of undefined'.

I try to understand but I can't find the problem.

Can someone help me ?

I think the problem is here because if I comment the render, is ok

<TimerInput value={this.state.seconds} handleChange={this.handleChange} /> <Minuteur seconds={600} libelle="Pâtes"/>
